My Hp laptop model G62 is not charging and it is not the cord

By lonniec1143 ·
My Hp laptop model G62 is not charging and it is not the cord. The computer will charge just fine for a few days and then it stops charging with the light by the plug will blink from white to red. If I pull the plug and put the plug back in the computer shows that it is pluged in, but only for a few seconds. I have changed the cord and the problem is still there.
The problem is the motherboard, the plugin jack, or the battery. Can I trouble shoot these problems so i do not have to replace them one at a time?

I just noticed that when the computer is in sleep mode or shut off it will charge to 100%.

RE:- Can I trouble shoot these problems

Yes you can the Service Manual for this model is available here

remember to remove the space from between hp and the .com for a working link.

Though depending on the battery I would try replacing that first as if it's dead it's likely to cause the problem. Though if the Charging Circuit on the M'Board has died that could just as easily be the problem here.

The battery is not completly dead, but it will be soon. I took the battery out earlier and put it back in. when I did the computer shut down. I can view the owners manual on my computer, but what kind of trouble shooting owuld be in there that would help me determine if the problem is the mnother board battery or the power jack

Will the computer work with battery removed?

by robo_dev In reply to My Hp laptop model G62 is ...

plugged in, obviously.

The most common fault on laptops is the power jack. On many HP models the power jack is a separate low-cost module that is not soldered to the motherboard, therefore can be fixed fairly easily without having to buy a new motherboard or do some soldering.

Power supplies: Note that many HP models have the 'low wattage' and the 'high wattage' power supply. If you have the low watt one, then the PC cannot be used and have the battery charged at the same time. With the higher wattage one, you can do both at the same time.

If you have an aftermarket power supply, many of the specs in terms of wattage are pure fiction, so most likely it will behave like a low wattage PSU.

Is battery full empty?

by derek.daski In reply to My Hp laptop model G62 is ...

If not empty, than try this:

Try to use the battery down to 5%. After that, turn computer on and go to bios menu and let it run for about half hour.

Than try to see if it will charge.

I just noticed that when the computer is in sleep mode or shut off it will charge to 100%. I will try your advise, but what will it do?

See my post above, if the lower wattage power supply is being used, the laptop will not charge the battery while it's powered on, that's how it works :)

Battery gets used up and there is wear on it. Use HWmonitor to see the wear level of the battery.

If is is more than 20%, than try to discard the energy it and charge it again. This will allow for better charging and should lower the wear level. This should be done every so often to get more life out of the battery.

Plus battery should be charge only when they are about 15% or less of power left. If you are not using the battery and only have it connect to the power cord, than best practice is to remove the battery until you need to go somewhere that will not be able to use the power cord.
